• a PDA nutrient medium containing spores of Botrytis cinerea, pathogen of gray mold of cucumber was placed onto the leaf surface of the cucumber plants. They were placed at 12°C under high humidity for 6 days after the inoculation, and thereafter control effect was checked. The diameter of infected area on the plants on which the agents had been sprayed was determined as the incidence of disease at the time of checking and the control value was calculated by Equation 1 based on the incidence of disease thus determined.
